WILLIAM CARTER, OF GLASGOW, SCOTLAND.

MACHINE FOR MAKING PAPER BAGS.

SPECIFICATION forming part of Letters Patent No. 626,319, dated June 6,1899.

Application filed December 2'7, 1897. Serial-No. 663,578. (No model.)

To all whom it may concern.-

Beit known that 1, WILLIAM CARTER,a subject of the Queen of GreatBritain, and a resident of the city of Glasgow, Scotland, have inventedcertain new and useful Improvements in Machines for Making Paper Bags,of which the following is a specification.

This invention relates to machines for making paper bags and such like;and it has for its object to improve and simplify the construction ofsuch machinery.

Vith this invention the operations of pasting the sheets or blanks,folding them, and pressing them can all be performed on the one machine.

In order that my said invention may be properly understood, I haveillustrated the same in the accompanying drawings, whereon- Figure 1 isa front view of the machine. Fig. 2 is a plan of the machine. Fig. 3 isan enlarged inverted plan view, and Fig. 4. a

similar side view, of the folding-knives and their actuating mechanism.Fig. 5 is a side view, Fig. 6 a front view, and Fig. 7 a back view, ofthe forming-block. Fig. 8 is a front view, and Fig. 9 a side view, ofthe paste vessel. Fig. 10 is a view of a paper bag made in the machine.The dotted lines y 11 indicate the bottom pieces y g) as turned over soas to form the bottom of the bag. Fig. 11 is a detail of the formingblock and table. Fig. 12 shows the paper sheet as laid upon thebaseplate of the machine. Fig. 13 shows the sheet with the bellows sidesa CL partially formed. Fig. 14. shows the bellows sides completelyformed by the turning over of the ends I) b, Fig. 13, of .the sheet ontop of the formerblock 31. Fig. 15 shows the bag-blank, Fig. 14, withits triangular bottom parts 0 0 formed by the turning over in the usualway of the triangular flap 38 of the block 31. Fig. 16 shows the bagcomplete, with the triangular parts 0 c pasted down, which can be doneby the machine described in the specification of my Patent No. 611,055.

Referring to the drawings, whereon the same reference-numerals whereverrepeated indicate the same parts, the machine consists of a table or bed1, which is supported upon standards 2 3 and provided underneath withtreadle or other suitable driving mechanism. Situated at one side of thetable is a paste vessel 4, which, as shown at Figs. 8 and 9, is oftriangular section, with a narrow opening or slit 5 for the paste topass through at the bottom onto the paper sheets. This paste vessel,which is capable of a vertical movement under the action of gravity orof a spring, is provided with guides 6 7, working in sockets 8 9 (seedotted lines, Fig. 8) in a plate 10, secured to the table. The guides 67guide the paste vessel in its movement. The sheets or blanks of paperto be pasted are simply laid evenly upon one another, with one edgebelow the opening 5 in the bottom of the paste vessel, which latter,owing to its weight or the action of the spring, bears upon them andpastes each one in turn. It will be easily seen that when the top sheetof the pile is removed the paste vessel sinks down onto the next sheetof the pile and pastes it, and so on until all the sheets are pasted.Adjustable gages 11 12 13 are provided on the table for keeping thesheets or blanks in place. As will be seen, the gages are slotted andclamped in place to the table by means of sockets fitted in the tableand screws with butterfly-heads 14, which pass through the slots of thegages and into the sockets.

Arranged at one side of the pasting device aforesaid is the foldingmechanism, which consists of two movable folding-knives 15 16, which arecapable of being traversed forward and toward each other, so as toperform the folding operation for the sides of the bags by means of arms17 17 18 18, having jaws 19 at their upper ends. pins 20, projectingfrom the sides of slippers 21, attached to the under sides of theknives. These arms 17 17 18 18 are pinned to two shafts 22 23, arrangedparallel with each other below the base-plate 24:, which latter issecured to the table by means of screws at 25. Each shaft has an arm 26,and these arms are connected by means of a chain, wire, cord, or suchlike 27 with a treadle 28. The knives 15 16 are automatically retractedafter each forward movement by means of torsionsprings 29 30, arrangedon the shafts 22 23.

Arranged between the folding-knives 15 16 is a bag-shaping andbottom-forming block,

The jaws grasp pivotconsisting of upper and lower plates 3-1 32. (SeeFigs. 5,6, and 7.) These platesare connected rigidly together by meansof a central rib 32 and rivets 33, and they are hinged at 34 to a pin35, secured to the base-plate 24.

The upper plate 31 has a taperedend 36 with;

a hole 37 for the finger at or about the center thereof, While the lowerplate 32 has a. correspondingly-shaped flap 38, but Without A recess 40is cut out of the flap to enable the bag to be easily slipped off theblock. The flap 38 isprovided with a projecting bar 41, which. The barmay be made.

the hole, hinged to it at 39.

serves as a handle. with a cutting edge, so as to cut the paper at thatpart when so desired. The spaces between the plates 31 32 of the blockat each side are sufficiently wide to admit of the entraneeof'thefolding-knives when the paper is being folded. The block is normallyheld in a vertical position (see Figs. 1 and 2) and up from thebase-plate by means of a spring a2, which'acts on a hook 43 fitted tothe block. In Fig. 2 "the dotted lines show the block in its downposition. I

Adjustable gages 44 {t5 are provided as guides for inserting the sheetsof .paper in the block-and folding mechanism.

25* are clamping-screws for the guides.

46 is a guide for the bar 41 at the end of the block.

Arranged at a con ven'iehtdistan'ce from the folding mechanism is thepressing device,

which merely "consists of a board or block' curved at its upper end andfaced with brass.

This block 47 is fitted to the table of the machine at the back of thefolding mechanism. After the bag has been passed through the foldingdevice and'properly folded it is drawn by the attendant over the upperedge of the pressing-block 47, so as to smooth down and press the folds.From the pressing-block the bags are allowed to fall 'down through ahole 4.8 in the table onto a chute 49, which delivers them into asuitable receptacle.

The parts of the mechanism are so made and fitted together as to beeasily taken asunder and cleaned.

The pasting device can also be adapted for pasting wrappers, sheets, andsuch like.

'When it is desired to paste two sides of a sheet, two pasting Vesselsmay be fitted on tn esame frame or bed.

The modus opercmdi is much the same as that usually adopted in thisclass ofmachines, viz: The paper sheet, after being pasted at one edgeby means of the automatic paster, is laid on the base-plate'ZeL (theknives beingreuected) and the block is brought down upon it, Thereafterthe knives areadvanced so as to force the paper at each side between thefplates of the block, and thereby form the bellows sides of the bag.This being dOneQthe free ends of thepaper (one of which ispastedas'aforesaid) are folded down 'on'top of the block and made toadhere together,and

then the knives "are retracted and the block brought to the verticalposition by the spring, when the triangular bottom parts are shaped inthe usual manner when making satchelbags. The bags are finally pressedon the block 47.
